[Monoclonal antibodies against tick-borne encephalitis virus glycoprotein: preliminary characterization].

Characterization of 12 clones of monoclonal antibodies (MAb) generated for the main immunogen of tick-borne encephalitis virus, glycoprotein E, is presented. The following MAb parameters have been determined: constants of binding with antigen, classes and subclasses of immunoglobulins, the activity in two variants of solid-phase enzyme-immunoassay, binding with protein A, and MAb behavior in serologic tests: hemagglutination-inhibition, diffuse precipitation in agar, and virus neutralization. The preliminary studies revealed the presence in these MAb of at least three groups of antibody complementary to various nonoverlapping sites on the structural virus glycoprotein. Further employment of these MAb in practical and research work is discussed.
